A Flipper Zero app that lets you type your own choices and let a roulette wheel decide — powered by the device's hardware true-random-number generator.
- Add up to 20 custom decisions (up to 20 characters each)
- Roulette-style animation with a fast phase that decelerates smoothly before landing
- True randomness via
furi_hal_random_get()(hardware RNG, not a software PRNG) - Scrollable decision list with context-sensitive on-screen hints
- Spin again or return to the list from the result screen
| Manage | Spinning | Result |

The app follows the standard Flipper Zero ViewDispatcher pattern with four views:
ViewIdManage ──[spin/add]──► ViewIdSpinning ──[done]──► ViewIdResult
▲ │
└──────────────────────────[BACK]──────────────────────────────┘
▲
ViewIdTextInput (keyboard)
A FuriTimer drives the spin animation by posting CustomEventSpinTick events to the ViewDispatcher, keeping all model mutations on the GUI thread.
